ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 612,780, dated October18, 1898.

Application filed F bruary 19, 1898. Serial No. 670,943. (No model.)

To all whom it may concern:

Be itknown that I, GAETANO P. MANSIONE,a citizen of the United States,and a resident of the city and county of New York, in the State of NewYork, have invented certain new and useful Improvements in Elevators, ofwhich the following is a specification, reference being had to theaccompanying drawings, forming a part thereof.

This invention relates to the general class of elevators in which areincluded machines, appliances, or devices for raising or loweringpersons or things.

The primary object of the invention is to provide improved devices foreffecting the raising or lowering of the car which shall be more certainin operation and less liable to derangement than devices heretoforeemployed for the purpose.

A further object is to provide for the extension of the elevator todifferent heights, as may be required from time to time.

The invention will be more fully described hereinafter with reference tothe accompany ing drawings, in which a convenient and practicalembodiment of the main features of the invention is illustrated, variousdetails of construction also being represented.

In the drawings, Figure 1 is a view in side elevation of an elevatorwhich embodies the improvements herein referred to, parts being shown insection and other parts being broken away. Fig. 2 is a top plan view ofthe same with the guides in section. Fig. 3 is a section on the planeindicated by the line 3 3 of Fig. 1.

The operating mechanism of the elevator may be supported in anyconvenient manner, as by a framework A of ordinary construction, whichit is not necessary to describe in detail herein. Supported by theframework or otherwise, if more convenient, are one or more guides B,which direct the elevator-car O in its movements and have also anotherfunction, which will be referred to hereinafter. For purposes of anordinary elevator four such guides are ordinarily provided, asrepresented in the drawings. These guides may be continuous, and theymay be constructed in any desired manner so far as the action of theoperating mechanism is concerned; but they are preferably tubular orhollow and slotted along one side, as shown at b in Fig. 1, in whichfigure the near side of one of the farther guides is exposed to view bybreaking away the upper portion of one of the guides nearer the eye andas shown also in Fig. 2. In order that the elevator maybe extensible tosuit diflferent heights, each guide is made in sections, as representedin Fig. 1. As there shown, the upper end of each section is providedwith an enlargement or socket b, into which the lower end of the sectionabove may be set. Any .suitable means may be employed for bracing thesections and for securing one to another, and in Figs. 1 and 2 arerepresented devices which enable the necessary bracing to be effectedwhen four guides are employed without 1'e sorting to external means ofsupport. As there shown, a brace or bar D is secured, preferably by apivot d, to each section near its lower end and engages the adjacentguide near the upper end of the corresponding section, as by means of apin or stud d, the end of the bar being slotted, as at CF. The bar D mayalso be provided with a downwardlyextending arm D, which, by means of apin 01 and slot d engages the section below and in line with that towhich the bar is pivoted- In this manner the guides are firmly bracedand the sections securely held together, while at the same time theaddition or removal of sections, as may be required according to theheight to which the elevator is intended to operate, is effected withoutdifficulty.

In place of the ropes or cables commonly employed in elevatorsheretofore constructed are substituted in this case toothed chains,

there being in the construction represented in the drawings one toothedchain for each corner of the car-platform 0. Each chain E is made up oflinks 6 e, which are pivoted one to another and are toothed on one ormore sides, being shown in the drawings as toothed on two oppositesides. The flexibility of the chain permits it to be coiled upon asuitable drum, and it is the function of the guide B to prevent flexureof the chain between the car and the operating mechanism, each chain inthe construction represented in the drawings moving freely within thecorresponding tubular or hollow guide B and being connected to the carby a pin or stud c, which travels in the slot 1) of the guide. In thisman ner the chain, having no backlash orlost n10- tion between itslinks, operates as an inflexible rack-bar, but, as above stated, iscapable of being coiled upon a drum.

The chains may be operated by any suitable gearing. The system ofgearing shown in the drawings comprises acommon drivingshaft F, actuatedby any suitable motor, from which motion is transmitted by a pinion fand on the one side by two intermediate gears f and on the other side bya single intermediate gear f to shafts The two shafts of each pair areprovided with intermeshing gears f so that they shall rotate together,and at their ends they are provided with pinions the pinions at thecorresponding ends of each pair of shafts j" meshing with the teeth onopposite sides of the corresponding chain E. By such means as those justdescribed the several chains E are operated together to raise or lowerthe car 0 as the case may be.

It is desirable to provide a take-up for each chain as it is releasedfrom the guide and the operating mechanism, and a device of thischaracter is shown in the drawings. As there represent-ed, each chain isconnected to a drum G, mounted loosely on a shaft g and caused to rotateabout said shaft by a coiled spring 9'' in order that it may take up thechain as it is released from the operating mechanism. In order that theline of the chain Within the guide may be always tangential, orsubstantially so, to the surface of the take-up, notwithstanding theprogressive increase of diameter thereof by reason of the winding of thechain upon the drum, the shaft 9 is shifted as the winding progresses.To enable this to be done, the shaft is mounted in arms H, which aresecured to a shaft h. An arm h on said shaft h is operatively connectedby a link or rod 7L Wltl1 a cam I. The latter is operated in anyconvenient manner, being represented in the drawings as formed in onecase in the face of a gear 6, mounted on a shaft t" and driven by apinion f on the main driving-shaft F, and as formed in the other caseinthe face of a disk i which is also mounted on the shaft t".

It will be obvious that the details of construction and arrangement ofan apparatus in which the invention is embodied may be variedconsiderably without departing from the spirit of the invention, andtherefore it is to be understood that the invention is not to be limitedto the precise construction and arrangement shown and described herein.

I claim as my invention 1. In an elevator, the combination of a car, atoothed chain to which said car is connected, a guide for said chain,operating mechanism engaging said chain independent of said operatingmeans and movable bodily away from the line of said chain, a take-up forsaid chain, and means to shift the position of said take-up.

2. In an elevator, the combination of a car, a toothed chain to whichsaid car is connected, a guide for said chain, operating mechanismengaging said chain, a take-u p for said chain, a swinging arm uponwhich said take-up is mounted, and a cam and intermediate connectionsfor shifting said arm.

3. In an elevator, the combination of a car, a toothed chain to whichsaid caris connected, a guide for said chain composed of sections, meansto secure one section in place upon another,and operating mechanismengaging said chain.

4. In an elevator, the combination of a car, chains to which said car isconnected, guides for said chains, braces extending from one guide toanother, and operating means for said chains.

5. In an elevator, the combination of a car, chains to which said car isconnected, guides for said chains, braces pivoted upon the severalguides and engaging adjacent guides, and operating means for saidchains.

6. In an elevator, the combination of a car, chains to which said car isconnected, sectional guides for said chains, braces pivoted upon theseveral sections of the several guides and severally engaging thesection below that to which each is pivoted, and the correspondingsection of an adjacent guide.

This specification'signed and witnessed this 16th day of February, A. D.1898.
